I wanna see a replay of the whole situation though. Do you think he would really just keep blowing someone up?

Yes.

*edit: I don't think it warrants a suspension, though. Call me mean, but it's paintball, people get shot. So, he shot a few extra people after the point. Call it playing on or whatever, but he didn't really hurt anyone or anything. Worst case, it just shows the NPPL they need to assess they way they handle the end of the match in those situations.
